Crate zksync_state

Execution of transaction in ZKsync Era

Structs

AsyncCatchupTask

A runnable task that blocks until the provided RocksDB cache instance is caught up with Postgres.

BatchDiff

DB difference introduced by one batch.

InMemoryStorage

In-memory storage.

PostgresStorage

ReadStorage implementation backed by the Postgres database.

PostgresStorageCaches

Caches used during VM execution.

PostgresStorageCachesTask

An asynchronous task that updates the VM storage values cache.

RocksdbCell

A lazily initialized handle to RocksDB cache returned from AsyncCatchupTask::new().

RocksdbStorage

ReadStorage implementation backed by RocksDB.

RocksdbStorageBuilder

Builder of RocksdbStorage. The storage data is inaccessible until the storage is Self::synchronize()d with Postgres.

RocksdbStorageOptions

Options for RocksdbStorage.

RocksdbWithMemory

A RocksDB cache instance with in-memory DB diffs that gives access to DB state at batches N to N + K, where K is the number of diffs.

SequentialCache

A generic cache structure for storing key-value pairs in sequential order. It allows for non-unique keys and supports efficient retrieval of values based on a key threshold. The cache maintains a specified maximum capacity, removing the oldest entries as new ones are added.

ShadowStorage

ReadStorage implementation backed by 2 different backends: source_storage – backend that will return values for function calls and be the source of truth to_check_storage – secondary storage, which will verify it’s own return values against source_storage Note that if to_check_storage value is different than source value, execution continues and metrics/ logs are emitted.

StorageView

StorageView is a buffer for StorageLogs between storage and transaction execution code. In order to commit transactions logs should be submitted to the underlying storage after a transaction is executed.

StorageViewCache

StorageViewCache is a struct for caching storage reads and contains_key() checks.

StorageViewMetrics

Metrics for StorageView.

WitnessStorage

ReadStorage implementation backed by binary serialized [WitnessHashBlockState]. Note that load_factory_deps is not used. FactoryDeps data is used straight inside witness generator, loaded with the blob.

Enums

PgOrRocksdbStorage

A ReadStorage implementation that uses either PostgresStorage or RocksdbStorage underneath.

StateKeeperColumnFamily

RocksDB column families used by the state keeper.

Constants

IN_MEMORY_STORAGE_DEFAULT_NETWORK_ID

Network ID we use by default for in memory storage.

Traits

ReadStorage

Functionality to read from the VM storage.

ReadStorageFactory

Factory that can produce a ReadStorage implementation on demand.

WriteStorage

Functionality to write to the VM storage in a batch.

Type Aliases

StoragePtr

Smart pointer to WriteStorage.
